Scope

This Standard specifies the methods for determining the colour fastness to domestic and
commercial laundering of various kinds of normal household articles. Industrial and
hospital articles may be subjected to special laundering procedures which may be more
severe in some aspects.
The colour loss and staining resulting from desorption and/or abrasive action in one single
(S) test closely approximates to one commercial or domestic laundering. The results of
one multiple (M) test may in some cases be approximated by the results of up to five
domestic or commercial launderings at temperatures not exceeding 70 °C. The M tests
are more severe than the S tests because of an increase in mechanical action.
These methods of this Standard do not reflect the effect of optical brightener that is
present in commercial washing products.
These methods of this Standard are designed for the detergents and bleach systems
given. Other detergents and bleach systems may require different conditions and levels of
ingredients.
